YARN-WINDING MACHINE.

Application filed March 26. 1923. Serial No. 627,619.

of VVhitinsville, county of Worcester and Commonwealth of Massachusetts, have invented certain new and useful Improveu'ients in Yarn-Winding Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

@ur invention relates to machines for winding yarn from a package upon a quill or bobbin, and especially to the devices e1nployed to guide and control the yarn; and it consists in certain novel features of conreference to the description of'the drawings, and to the clanns to be hereinafter g ven.

Reference is to be had to the accompany iz'zg drawings forming part hereof, whcreiu: l igure 1 is a front View of the driving end of a winding machine embodying my invention; Figure 2 an end elevation thereof: Figure 3 is asectional elevation on line 33 of Figure 1; Figure 4: is a partial plan view of Figure 1; Figure 5 is an enlarged sectional elevation of the driving means of the tablesysupportin'g the supply package; Figure 6 is; an axial section of the yarn tension and Figure 7 is a perspective view of the yarn guide and traverse rail.

Like reference characters refer to. like parts in the several views. of the drawings.

The winding machine in construction comprises spaced apart end frames 1 (only the head end being shown in drawings) andfione or more intermediate. supports 2, all rigidly connected by the upper rails S and lower rails 4 on each sideiof the machine. The lower rails 4; serve as supports fora plurality of winding members or spindles 5 for supporting the receiving bobbins. 6. Rotary motion is imparted to the winding spindles 5 from the driving cylinder 7 by the bands 8. The packages 9,.c0ntaining the supply of yarn to be rewound on bobbins 6, are supported onv rotating tables 10, the packages 9 being maintained on the centre of the tables 10. by the skewers 11 (Figure 5) projecting loosely into-the central bores of the packages.

skewer 111s in a fixed relation with the centreof journal 12- of the rotary table 10. The journal is preferably formed integral The with the stand 13 supported by the rails 3.

Although different means may be used for imparting rotary motion to the package tables we prefer to make use of a friction drive col'nprising the leather faced pulleys 14 in frictional contact with the peripheries of the package tables 10. The pulleys 14 are loosely mounted on the revolving shafts 15.- The hub of the pulleys 14 is provided with a radial slot 30 as shown in dotted lines in Figure 5. Collar 16 in fixed relation with the shaft 15 is provided with a lug 31loosely engaging with slot 30, thus transm tting the rotary motion the shaft 15 to the friction pulley 14.. Av compression spring 17 encircles the hub of the pulley, one end of which abuts against the web of pulley and the: other against. the face of the collar 16. thus maintaining the pulley 14 and package table in proper frictional relation with each other. Rotary motion is imparted to the shafts by a suitable train of gears driven from the shaft 18 which receives its motion through another train of gears from the driving shaft 19 of the machine.

In operation the yarn 20 contained on'the supply packages Qis drawn over the fixed guide rods 21 located centrally above the supply packages, thence the yarn is drawn through the tension device 22, of common construction, and guide eye 27 and wound onto the receiving bobbin. 6. The rotary speed of the supply )ackage is very small as compared with that of the receiving 'bohbin'on the winding spindle, being just.

sufficient to slowly unwind the *am from thepackage thus preventing entanglement and consequent breakage. The tension devices 22. one for each strand of yarn, are fixed to the shafts 23 slowly revolving in bearings supported by brackets 24 fixed to uprights 25 on top of the machine. Motion is imparted to shaft 23 from shaft 18 by suitable transmitting means. The rotary motion of the tension reduces the strain on the yarn while :it is being.

woundonto the receiving bobbin.

The winding of the yarn onto the receiving bobbin is effected by the rotation of the spindle supporting the bobbin drawingsthe yarn from its supply package over the guide rod 21 through the tension 22 and guide eye 27 and then wound on the receiving bobbin 6. The'guide eye 27 is fastened'to a'rail or hair 26 which has a reciprocating motion actuated by the bobbin huildei umtinn common to spinning and twist ing nmvhinus.

We claim 1. In a yarn winding nmehine having: a. plurality of winding HuHllHlH. mtntnhlo tables supporting the supply pnekuges. frietion pulleys emu-ting with the peripheries 0f suitl tables to rotate them. revolvingshults centrally located henenth the rotary tuhlesn sziid friction pulleys being loosely mounted thereon. cellars fixed to suitl shafts emperuting With the hubs of the friction pulleys, and compression springs between the collars and the pulleys.

2. in a yarn Winding machine having a plurality of Winding members, rotatable tables supporting the supply packages frier tinn pulleys count mg with the peripheries or Sultl tables to rotate them. revolving shafts lmntml heneuth the rotary tuhles, Said ii'iiclin testinmnv wherenf, we have signed this specification.
